Three Workers Die After Inhaling Toxic Gas at Tata Factory Producing Apple iPhone Components in India

Three contract workers have died after inhaling toxic gas while carrying out inspection activities at a Tata Electronics manufacturing facility producing components for Apple’s iPhones in Tamil Nadu, southern India.

The incident reportedly occurred late Monday at the company’s manufacturing plant in Hosur, located in the Krishnagiri district, where the workers were part of a team assigned to cleaning and maintenance activities at an effluent treatment plant.

A senior district official, Dinesh Kumar, confirmed the incident, explaining that the workers inhaled gas while inspecting an external nano-filtration tank within the facility.

According to Kumar, the victims were among several contract employees assigned to clean the effluent treatment plant (ETP), a facility responsible for treating industrial wastewater generated during manufacturing operations.

The three workers reportedly became exposed to the gas during the inspection exercise and were subsequently rushed to a private hospital for emergency medical attention.

However, doctors declared them dead on arrival.

Authorities have yet to disclose the identities of the deceased workers or provide further details about the exact nature of the gas involved in the incident.

The circumstances surrounding the fatalities are expected to form part of the investigation into the incident, particularly the safety arrangements provided for workers undertaking cleaning, inspection and maintenance activities around industrial treatment facilities.

The deaths have raised fresh concerns about workplace safety in India’s expanding electronics manufacturing industry, especially regarding the protection of contract employees who often undertake industrial cleaning and maintenance operations.

Tamil Nadu’s Industries Minister, Virudhai Magal Keerthana, said the state government would ensure that the incident was thoroughly investigated.

In a statement published on social media platform X, the minister said appropriate action would be taken based on the findings of the investigation.

Tata’s Growing Role in Apple’s Global Supply Chain

Tata Electronics, a subsidiary of the Tata Group, has become a major manufacturing partner of Apple as the American technology company continues to expand its production operations outside China.

The company accounts for approximately 40 per cent of iPhone assembly in India, while Foxconn handles much of the remaining production.

India has increasingly emerged as one of Apple’s most important manufacturing destinations, with the country now accounting for approximately 25 per cent of global iPhone production.

The expansion forms part of Apple’s broader strategy to diversify its manufacturing operations and reduce its dependence on China amid changing global trade and supply-chain conditions.

The growth of the industry has also attracted significant investment into India’s electronics sector, with major manufacturers establishing facilities to produce smartphones, components and other technology products for international markets.

Tata Electronics has been central to this expansion, strengthening its manufacturing capacity and increasing its involvement in Apple’s production network.

However, the latest incident could bring renewed attention to the working conditions and safety standards maintained at facilities involved in the production of electronic components.

Tamil Nadu’s Position as a Major Industrial Centre

The incident occurred in Tamil Nadu, one of India’s leading industrial and manufacturing states.

The state hosts production facilities belonging to several major international companies, including Foxconn, Hyundai, VinFast and BMW.

Its growing electronics and automobile industries have made it an important destination for foreign investment, employment generation and industrial development.

Hosur, where the incident occurred, is one of the state’s recognised industrial centres, hosting several manufacturing companies and industrial facilities.

The presence of major international manufacturers has contributed to the area’s economic growth, while also increasing the importance of effective industrial regulation, environmental protection and occupational safety.

The latest fatalities are likely to intensify discussions about the need for strict compliance with workplace safety regulations, particularly in facilities where employees handle industrial chemicals, wastewater treatment systems and potentially hazardous gases.

Previous Setbacks at Tata’s Hosur Operations

The latest incident comes after a series of operational and environmental challenges affecting Tata’s manufacturing activities in the Hosur area.

In 2024, a fire disrupted production at a Tata components manufacturing facility, affecting its operations.

Earlier in 2026, state authorities raised concerns over alleged groundwater contamination linked to the facility and warned that the plant could face closure.

However, the proposed shutdown was subsequently dropped.

In another development, a ransomware attack on an adjacent iPhone manufacturing facility within the same industrial compound reportedly resulted in the leakage of confidential documents relating to Apple’s then-unreleased iPhone 18 Pro.

These incidents have placed Tata’s manufacturing operations under increased scrutiny, particularly regarding operational security, environmental compliance and industrial safety.

The deaths of the three contract workers have now added another serious concern to the challenges surrounding the company’s manufacturing activities in the region.

Investigation Expected to Establish Circumstances of Deaths

Attention is now focused on the investigation into how the workers were exposed to the gas and whether adequate safety precautions were observed during the inspection of the external nano-filtration tank.

Authorities are also expected to examine the working conditions at the effluent treatment facility and establish whether the workers were provided with appropriate protective equipment and safety procedures for the assignment.

The findings could determine whether any violations of industrial safety regulations occurred and what measures should be introduced to prevent similar incidents.

Meanwhile, the incident has renewed calls for stronger workplace protection, proper training and strict enforcement of safety standards across India’s rapidly expanding manufacturing industry.

As India continues to strengthen its position as a global electronics production hub, the latest tragedy highlights the importance of ensuring that industrial growth is accompanied by adequate protection for the workers responsible for sustaining the sector.
